WILLIAM FITZ CHARLES MASON McCARTY, OF EAST PLEASAN'I'VILLE, NEW YORK.

COMPOSITION OF MATTER TO BE ADDED TO INTERNAL-COMBUSTION-ENGINE FUELS AND TO BE USED FOR OTHER PURPOSES.

No Drawing.

To all whom it may concern:

Be it known that 1, WILLIAM F. C. M. MG- CARTIQJJ. citizen of the United States, residing at East Pleasantville, in the county of \Vestchester and State of New York, have invented certain new and useful Improvements in Compositions of Matter to be Added to InternaLCombIlstioil-Engine Fuels and to be Used for other Purposes, of which the following is a specification.

This invention relates to a novel composition of matter for use in the arts and particularly for use as a solvent of oils, fats, Waxes, wool fat and the like, and for the prevention and removal of carbon deposits, scale or like incrustations in the cylinders of internal combustion engines.

In the preferred embodiment of my invention, I provide a mixture of acetone, ether, (either ethyl or methyl ether) hydrogen dioxid and methyl nitrate, thereby producing acomposition Which is freely miXable with oils such as hydrocarbon or mineral oils, and Which may be used as a solvent therefor. To this mixture may be added a small quantity of a solution of nitroglycerin in ethyl alcohol where the composition is to be used for the prevention or removal of deposits in internal combustion engines.

The proportions in which the materials are brought together is preferably as follows: acetone, 1 gallon; ethyl ether, 3 to 5 gallons; hydrogen dioxid, 12 ounces; methyl nitrate, 4; ounces.

Where nitro-glycerin is employed in the mixture it is added thereto in the proportions of one-half ounce of nitro-glycerin dissolved in a quart of ethyl ether to six gallons of the mixture.

In producing my composition, I prefer to first add the hydrogen dioxid to the acetone. I stir these materials until a homogeneous mixture or solution is obtained. I then add the methyl nitrate previously dissolved in from five to ten times its Weight of ethyl ether. The ethyl ether is then added and the composition is ready for use.

\Vhere nitro-glycerin is employed in the mixture, it is preferably added last.

If I employ methyl ether in place of ethyl ether it is added in a gaseous state to the acetone as long as it Will dissolve freely therein at ordinary atmospherlc temperature or a similar quantity of the methyl Specification of Letters Patent.

Serial No. 785,583.

ether in a liquefied condition may be added to the acetone.

In using my composition for the removal of deposits from the cylinders of internal combustion engines, the composition is placed in the engine cylinders and is preferably allowed to remain therein for several hours, the engine crank being rotated from time to time to move the pistons in the cylinders. The composition may then be drawn off, but better results are obtained by starting the engine and permitting the small amount of the composition in the cylinders to be ignited, the high temperature resulting tending to consume the remaining carbon. I may however, advantageously allow a small. amount of my composition to be drawn into the engine cylinders with the fuel or I may add the composition to the fuel itself before it is drawn into the engine cylinders, in which case it is added to the fuel in the preferred proportion of from one to five parts of the composition to ten parts of the fuel, although the proportion in which the composition is added to.

the fuel may be widely varied, a smaller or larger proportion being employed. The particular amount added in each case must of course depend upon the observed characteristics of the mixture; that is, the way in which it acts in the engine cylinder. The various oil fuels, of course, act quite differently in the cylinders of internal combustion engines using liquid fuel. Where my composition is added to the fuel the resulting solution may be separately piped to the manifold but the composition is preferably mixed With the main body of the fuel and drawn therewith into the motor through the carbureter.

While I have described in detail the preferred practice of my invention, it is to'be understood that the proportions of the ingredients may be Widely varied and that equivalents of such ingredients may be employed, Without departure from the spirit of my invention or the scope of the subjoined claims.

Having described my invention, I claim l. A composition of matter for the pur poses specified comprising acetone, ether, hydrogen dioxid and methyl nitrate.

2. A composition of matter for the purposes specified comprising acetone, ether,

hydrogen dioxid, methyl nitrate and a high In testimony whereof I aflix my signature explosive. in presence of two witnesses.
